1 Corinthians 8:6 But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
There are some wonderful benefits to being saved and being in Christ.
Acts 17:28 For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring.
All true riches are in Christ. The things that last, fulfill, and enrich our lives are all in Christ. Not money, not clothes, not position, nor any other thing can satisfy. Only Christ's love can bring full contentment, peace, and purpose.
In Christ, you can know how best to live as a young person, how to choose a mate and raise a family, how to prosper, what to do in times of trouble, what to do when you fail and everything you need to help you be the best you can be.
All real knowledge and wisdom is in Jesus and in learning of Him. Everything you need to know to have the best life comes from knowing Him and knowing of Him.
